In the drawings, numeral 1 indicates the Leading from the opening 6 in each jaw 1 frame in which is supported a horizontally 5 is a conduit 15 into which nails are adapted to be deposited points foremost from a feeding chute 16. The feeding chute 16 comprises a member having a slit in which the body of the nails is received, the heads of the nails resting on the top portion of said chute as clearly illustrated in Fi g. 9 wherein said nails are identified by reference character N. Passage of the nails from the feeding chute 16 is controlled by 368118 of a vertically disposed wheel 17 suitably mounted for rotation on a standard 18 forming part of the frame of the machine. The wheel 17 is in the nature of a disk having a plurality of cut-outs 19 through which the nails may pass from the chute 16 to the con-- duit 15 on the other side of the said wheel. The nails do not pass directly into said conduit 15 after passing through said wheel 17 but are held suspended on a pair of fingers 20 forming in effect a continuation of the chute 16 as more cle rly shown in Figs. 8 and 9, the fingers being bent in the diree tion of rotation of the conduit 15, which latter has a cutaway part 21 in its forward face, the arrangement being such that as the conduit 15 moves beneath the nail suspended on said fingers the nail is pushed off said fingers and dropped into the said conduit 15 and into the opening 6 in the jaw 5 as clearly shown in Fig. 8. The nailpassing wheel 17 has its openings 19 of such shape that picker fingers 22 are provided, the opening between the end of the picker finger and the adjacent portion of the wheel being only sufficient to allow a nail to pass therebetween. The finger 22 is beveled on that face remote from the chute 16 (see Fig. 8) so that after a nail has passed between the opening adjacent the tip of the finger it will be pushed laterally of said wheel onto the nail-holding fingers 20 at the end of the chute. The beveled portion of the finger is indicated by reference numeral 23 in Fig. 8.

The nail-passing wheel 17 is adapted to be rotated by the work carrier 4 as the c0nduit 15 thereon passes the end of the chute 16. The rotating means may conveniently take the form of lateral lugs 2% on the wheel 17 which are adapted to be struck by a lateral projection on the conduit 15.

The means for supplying nails to the feed ing chute 16 will now be described.

As shown in Fig. 2 the conduit 16 is a branched member which extends upwardly forming a single member, the end of which is positioned adjacent the loop 25 of a. belt 26 which passes around a pulley 27 at said loop 25 and around a pulley 28 remote therefrom in a horizontal direction. The belt 26 is slit longitudinally as at 29 to form a plurality of belt members and to provide an opening into which the body of the nails may be received but not the heads thereof, the heads remaining suspended from the top of the belt members. The belt members may conveniently consist of a pair of coiled springs arranged side by side, the pulleys 27 and 28 being suitably grooved to hold the sprin elements in proper relationship as regards the slit as will be readily understood. The pulley 27 is provided with an annular slot to correspond with the slit 29 in the belt so that the body of the nails may extend down into said annular slot as will be readily understood. As the belt is moved toward the pulley 27 the nails will leave the belt and be received on the adjacent end of the chute 16 as will be readily comprehended by reference to Figs. 4; and 5. After the nails are received on the chute 16 they slide down the same and fill the respective branches constituting the lower end of the chute.

The endless belt 26 is located within a. horizontally disposed drum 30, one end of the drum being open as indicated at 31. The interior of the drum is provided with vanes 32 for elevating nails and depositing them on the endless belt 26. As the nails fall on the belt 26 some of them will pass points foremost through the slit 29 therein and be suspended thereon by their heads as shown in Fig. 4.. Suitably mounted in fixed relation to the horizontal run of the belt 26 is a baille plate on which the nails are first received after dropping from the vanes 32 within the drum. The nails slide down this plate onto the belt as will be readily understood. Disposed over the lower run of the belt is a second plate 3% which serves to prevent nails from falling thereon. Arranged below the upper run of the belt 26 adjacent the front pulley 27 is a pair of guiding fingers 35 which serve to direct the points of the nails into the annular slot in the said pulley 27.

As shown in Fig. 11 the pulley 27 may consist of independent members having their adjacent fac s dished as at 27' to provide clearance for the body of the nails projecting down from the belt.

The drum is supported in any suitable manner in the machine frame and is conveniently driven by rollers 10 suitably geared to a horizontally disposed shaft 41 which is driven from the main shaft 2 by suitable connection as a belt 42.

Arranged at the open end of the drum is an inwardly projecting annular brush 45 which is adapted to wipe over the upper run of the belt adjacent the pulley 27 to wipe off any nails which are not properly positioned within the slit 29 of the belt 26.

The pulleys 27 and 28 are maintained in spaced relation by any suitable means as bv spacing roos -16. The pulley 27 mounted on the shaft 4: 1 which, as already indicated. is driven from the shaft 2 by a belt 42. I

The drawings show the invention in a more or less diagrammatic manner but the operation thereof will be readily understood from the preceding description;

What I claim is:

In combination, a rotatable drum, spaced belt members within said drum providing a slitthroughwhich the bodies of the nails may pass but not the heads thereof, means Within said drum for elevating nails and depositing them on said belt members, and a radially disposed brush at the open end'of said drum adapted'to Wipe over thebelt- GLEN 'PARKS;
